    摘要:

    摘要:研究了以正硅酸乙酯(TEOS)、三氯生和γ-胺丙基三乙氧基硅烷(KH-550)为原料制备的缓释型有机/无机复合抗菌材料的耐热性能。采用SEM、FTIR和DSC/TG等方法表征了样品的颗粒形貌、表面基团和热稳定性,通过抑菌圈实验表征了经灼烧后样品的溶出抗菌性。研究发现该有机/无机复合抗菌材料具有较好的耐热性能,在400oC下加热30min仍可部分保留其抗菌性能。本文还将样品用于粉末涂料中,获得了具有良好抗菌性能的粉末涂料涂层。

    Abstract:

    Abstract:Sustained-release antibacterial organic/inorganic composite material was prepared with TEOS,trichlosan and γ-aminopropyl triethoxy silane (KH-550), and its thermal stability was investigated. SEM, FTIR and DSC/TG methods were employed to investigate the particle morphology, surface functional group and its thermal stability. Bacteriostasis circle experiments were conducted to assess the dissolving antibacterial performance of the calcined samples. It was revealed by the results that the as-made organic/inorganic composite antibacterial material exhibited good thermal stability. The dissolving antibacterial could be partially preserved even after calcination under 300oC for 30min. The as-made samples were also applied in powder coatings, and coatings with high antibacterial ability were obtained.
